Anti-Markovnikov's rule :-

• Anti-Markovnikov's rule say that hydrogen is attached where hydrogen is less and halogen is attached where hydrogen is more.
• Anti-Markovnikov's rule is also known as Kharasch's effect or peroxide effect.

Finkelstein reaction :-

• Alkyl iodide are often prepared by the reaction of alkyl chloride/bromide with NaI in dry acetone. This reaction is known as Finkelstein reaction.

Sandmeyer's reaction :-

• The diazonium salt is prepared by treating aniline dissolved in cold aqueous mineral acid with an aqueous solution of sodium nitrite at low temperature (0-5°C).
• Bromo and chloroarenes can be prepared by treating a freshly prepared diazonium salt solution with cuprous bromide or cuprous chloride.

By the action of Thinoyl chloride :-

• Chloroalkane is prepared by refluxing the alcohols with SOCl2 in the presence of pyridine.
• Best method for preparation of Chloroalkane.
